Stock Cylinder Head Flow Numbers

[turbobuick1]

I'm wondering if anyone has any flow bench numbers for untouched stock 86-87 heads? Ideally, different cfm values at multiple valve lifts. Also, and I'm a little doubtful if anyone has this info, but stats on intake port length, avg. diameter, and volume? I really appreciate any info anyone might have on this, or if someone could reference me to a link or website or something.

Well, i did find some flowbench numbers for turbo buicks, among many other different engines. As for accuracy, who knows, so please, if anyone has any more info on stock flow numbers...
